WATER SYSTEM.

Continuation of application Serial No. 69,312, filed November 16, 1925. This application filed February 28, 1927.

This invention relates to water supply systems which include a pump for delivering Water into a storage tank against air pressure. The present application is a continuation of my application, Serial No. (59,312, tiled November 16, 1925.

One of the objects of the present invention is to deliver automatically, a quantity of air to the tank in order to compensate for the air which has been absorbed by the water in the tank. In the present invention this aim is accomplished by providing means responsive to the flow of water from the pump to the tank for causing air, which has been collected in a small auxiliary tank to be forced by the water delivered from the pump into the pressure storage tank. The invention provides for automatically venting and draining the auxiliary tank when water ceases to flow trom the pump to the storage. tank so that air may be accumulated in the auxiliary tank preparatory to the next operation of the pump.

Further objects and advantages of the present invention will be apparent from the following description, reference being bad to the accompanying drawings. wherein a preferred form of the present invention is clearly shown.

In the drawings:

Fin. 1 is a diagrammatic vicw illustrating a pumping system embodying: the pres ent invention;

Fig. 3 is a portion of a sectional view similar to Fig. 2 showing one of the valves open.

Fig. 4 is a sectional view on the line 4 4 of Fig.

Referring to the drawings, designates a power head which comprises an electric m0- tcr 21 and gearing within the power head for converting the rotation of the motor into reciprocatwy motion for operating a pump which is located within a well casing; 22. The well casing includes a discharge head 23 providingthe outlet ot' the pump. as is known to those skilled in the art. This discharge head is connected with a pump outlet pipe 2%. an L a union 26 and a pipe 27 with the cover :28, or bottom plate.

Serial No. 171,515.

for a small auxiliary tank 29. The upper end of the tank 2t) is connected by pipe 30 with a check valve 31 which in turn is connected by pipe 32, union 33 pipe 3 L 35, pipe 36 and L 37 ith a pressure storage tank 88 having an outlet 39. The pumping apparatus may be started and stopped manually, but preferably by means which is responsive to the pressure within the storage tank 38. This controlling apparatus is not shown, as various forms thereof are well known to those skilled in the art.

The means for ventingand draining the auxiliary tank 29 when water ceases to flow from the pipe 27 into the tank 29, comprises a flow-controlled, tubular element 40 which is vertically movable within the pipe 27 and is guided thereby. The upper end of the member 40 closed and is attached to a. rod 41. the upper end oi which carries a disc 4-2. The pipe :27 is provided with a plurality of slotted side openings, one ot which shown at 43. The size and number of these openings are such that there will be sutlicient pressure maintained against the element 4 0, while the pump is (mi-rating, to maintain said element nauthe upper end of pipe 27. as shown in Fig. 2. \Vhen water ceases to flow from the pipe 27, the flow-controlled element 40 will descend so as to nurse the disc 42 to engage a lever ll which is pivoted a 45 upon a bracket a l) attached by screws 4? to the bottom over plat-e 28 oi the tank 29. The lever i l has pivot pins 44 and 44 which are passed through holes 48 and 4-5) in links 48 and 49 respectively, forming lost motion connections with the links. The link 48 is connected to a dra n valve 50 which seats on a bushing 52 and the link 49 is connected to a vent valve 51 seating on a bushing .33. As seen in Fin". 2, the hole 48 is larger than the hole 4:9, in order to provide more lost motion between the drain-valve link and the operating lever than between the vent-valve link and the lever.

The lever 44: has a weighted portion 54 which seats the valves when the weight 40 is up. bit when the water ceases to flow from the pump into the tank. the flow-controlled member 40 will descend and will cause the lever 44 to move clockwise. thuslifting the valves 50 and 51 from their seats. This operation will. cause water to flow from the III tank 29 through a drain passage comprising the bushing 52 and a tubular boss 55 which conducts water into a drain chamber 56 provided by the base plate 28 and closed by a cover 57. Drain chamber 56 is connected by pipe L 59, pipe 60, L 61 and pipe 62, with the discharge head 23 which is provided with a passage (not shown), tor draining water into the well casing 22. lVhile water is being drained from the tank 29, air is admitted to the tank 29 through the U-pipe 65, standpipe (36, drain chamber 56 and bushing The bushing 53 extends within the tank 29 above the bushing The water pressure at the level of the upper end of bushing 52 is greater than at the level of the upper end ot' bushing 53. Consequently, water will flow through passages and into the drain chamber 56 while air passes up the bushing! 53 and through any water which may be above the bushing 53. The lower end of pipe 55 is below the lower end of pipe so that air may pass from pipe (36 to pipe 53 above the surt'ace of water in the chamber 56.

hen the pump operates again, the fiow controlled member 40 Will be elevated, thus releasing the weight 54 to cause the valves and 51 to be closed. The air trapped within the auxiliary tank 29 will be delivered into the storage tank 38 by the water which forced by the pump through the tank 29 and into the tank 38.

As will be seen in Fig. 2, the vent valve 51 is smaller than drain valve 50 and its point, ot connection 4st to the lever is closer to the pivot 45 than pivot 44 which opens the drain valve 50. Likewise the disk 42 acts on the lever 1'4 at a relatively great distance from the pivot 45 while both links have relatively short lever arms with respect to the pivot 45. There is also a greater amount ol lost motion between the drain valve and the lever than between the vent valve and the lever.

It. when the pump stops, due to the operation of the pressure device connected with the storage tanks, the pressure within tank .29 and pipe 27 is high, this pressure acting on the upper surfaces of the valves. seats them with great force. The moment tending; to open them is the weight of -10 multipiie-zl by the lever arm VI. The moment; seating the vent valve is the pressure times area of the 'alve times lever VP. But the area of the valve being small and VP being short. the moment of the pressure is less than the moment of the weight 40. Consequently the vent valve. is opened. Due to the lost mo tion connection 44 18, the drain valve remains seated and exerts no force on the lever it until after the vent valve has opened. As soon as the vent opens, the pressure in the ta k is released and consequently the only force holding the drain valve shut is the moment of the Weight of the linkage to the left of the pivot d5. This is less than the moment of Weight 40. Consequently the drain valve opens.

It will also be noticed that the vent valve is near the bott "111 of the tank. Therefore when the pump begins to operate, as soon as a relatively small amount of air has been t'orcrd out of the air charging tank, water will cover the valve and seal the opening. ionsequently the rest of the air can be forced into the storage tank under very high pressure without any loss from leakage.
